Making seawater potable

Desalination is the process of removing salt from seawater, making it drinkable. This is done either by boiling the water and collecting the vapor (thermal) or by pushing it through special filters (membrane).

What happens if you boil sea water?

Thermal distillation involves heat: Boiling water turns it into vapor—leaving the salt behind—that is collected and condensed back into water by cooling it down. The most common type of membrane separation is called reverse osmosis. Seawater is forced through a semipermeable membrane that separates salt from water.

How do you make drinking water from sea water?

Why is desalination bad?

What are the environmental impacts of desalination? … Desalination has the potential to increase fossil fuel dependence, increase greenhouse gas emissions, and exacerbate climate change if renewable energy sources are not used for freshwater production.

Are we running out of water?

While our planet as a whole may never run out of water, it’s important to remember that clean freshwater is not always available where and when humans need it. In fact, half of the world’s freshwater can be found in only six countries. … Also, every drop of water that we use continues through the water cycle.
